I can't seem to find a way to see everyone that is in my campaigns. Like I have 5 people with characters in one but it shows I have 8 people in the campaign. How do I see those other people and remove them if need be?

When you look at the characters in your campaign, you will see the Player name under the character name. This will tell you which players are in your campaign.

If it says Unassigned, then that means that one of your players has created the character and then Unassigned it.

Yes again 5 people have characters in the campaign that I can see. But the campaign says there are like 7 people in the campaign... I can't see who they are to even begin to remove them.

Are you seeing the player count on the "My Campaign" page?

Are you counting yourself (and possibly a second non-GM account of yours) in the count of 5 players?

But I agree it is strange that there isn't a way to see which PLAYERS have clicked on the invite link to join the campaign.

(I don't see how the My Campaign page can also list more players than there are characters in the campaign.)

Now it seems your getting it. It is really odd and since that's the case which number do I go off of. The one on the campaigns page or the number of people I can see that has characters made and assigned in the campaign.
